Question

Short note on carbanion.

Answer 1

Answer :

Carbanion -

The organic species containing negatively charged Carbon atom are known as carbocation.

It is of three types - Primary carbanion, secondary carbanion and tertiary carbanion.

The stability of carbanion can be explained either by inductive effect or by hyperconjugation.

i.e., $\boxed{1^{\circ}>2^\circ>3^\circ}$

Characteristic of Carbanion -

1. In carbanion, carbanionic carbon are $sp^3$ hybridised containing three bond pair and one lone pair so it's geometry will be trigonal pyramidal.

2. It is formed by heterolysis.

3. In carbanion, the carbon atom are complete containing a lone pair so it behaves as an nucleophile.

4. In this, all the electrons are paired so it is dimagnetic in nature.

Answer 2

Heya mate
The answer of ur question is

Carbanion are the anions in which the carbon is tetravalent .
In this the carbon atom form 3 bonds and bear a formal negative charge .
Molecules of carbanion are sp3 hybridised.

Examples of carbanion are - Methide ions , Phenyl anions , methyl anions and acetylide ions ...

hope it helps
